Houseplant Bulbs

A bulb is that part of a plant that contains the tender shoots of a new plant. Many flowering plants such as tulips, hyacinths, and lilies are propagated by bulbs. The energy a new plant needs to develop is stored in the bulbs. There is a large variation in the size of house Plant BulbsSome indoor and outdoor plants are grown from bulbs. Plant Bulbs, swollen underground stems with scaley leaves, store food and provide energy for the plants we see above ground. They are also used for propagation. Bulbs should be planted deep enough in the soil so that they are totally covered. How deep you plant the bulb, depends upon the plant variety. There are true bulbs and there are rhizomes, corms, and tubers that are sometimes included as types of bulbs. Bulb plants that keep their leaves all year are used as houseplants. Bulb plants that lose their leaves after they flower and become dormant are usually used as outdoor plants. Certain environmental conditions, such as the change in temperature from winter to spring, encourage bulb plants to produce flowers. Once the plant has finished flowering and is only a green leafy plant, the plant rests for a few months. During this time, the bulb absorbs and stores nutrients from the soil to help the plant flower again the following year. Some indoor plants that grow from bulbs are: amaryllis, calla lily, caladium (tubers), False Shamrock plant (Oxalis triangularis), begonia (tubers), and cyclamen (corms), cyclamen (tubers).. They can be as small as a pea or as large as 15 pounds (7 kg).  Plants that develop from bulbs produce leaves and flowers each season, then gradually die back and go dormant for a few months. During this dormancy or resting period, the plant stores the nutrients that will help it bloom again the following year. Bulbs can be forced to bloom almost any time indoors, brightening up your house during the cold winter months.
